Right to passage

The international law does not clearly define the control of the right to passage.

Even though if defined who could exercise control over the passsge is the question 

The strait of Hormuz now blocked by the country of iran is widely condemned by the United Nations

What could be reason is it really war or anything else for the condemning nations 

First was this opposed by the Russia china and India?

What could be the reasons whether is this the only war that affects the lives of people or the lives of people was immaterial in earlier and on going wars .

Was Iran doing the right thing by blocking the strait of hormuz , any nations who s threatened could defend themselves but is the Real defence mechanism 

What is the strait jacket formula in war .

Ukraine and Russia was into war for the last two years was anyone worried other than the two 

anyhow the only affected would the civilians in the war and not the heads so many battered displaced does it even matter ?

Put your thoughts on this and I strongly condemn any act whosoever and whatsoever taking lives of people.
